Question
Hi Jean,

I'm back again. I am bothered with this Ingres error
message that sometimes halt our operation.

Here are the error messages...
E_RD0043 No more space in cache to build or extend a
descriptor block.
E_UL0104 No more space in the hash table.
E_PS0F01 The descriptor cache is currently full. Try again
later.

A restart on the server fix the problem. But i just want to
know what causes the error and if there are ways to
increase this descriptor cache.

Thanks in advance,
JB  

Answer
Hello JB,

Nice to read you again :-)

It seems your RDF resources are exhausted (RDF stand for Relational  Data Facility, ie it retain your table & index definition).

Please read this link http://www.webservertalk.com/archive288-2005-3-947500.html for knowladge.

I suggest you to "play" with one of these parameter :
rdf_max_tbls
rdf_memory
rdf_tbl_cols
rdf_tbl_synonyms

particulary rdf_max_tbls (depend on how many tables you have in your DB).

Hope this help you,
Regards,
